Initialize virtual volumes with no allocated initial space to prevent consuming all space available during volume creation. The behavior of virsh has changed, by default in the past the virtual volumes were initialized automatically with no initial allocated space, while with recent versions we need to specify explicitly to not allocate initial space for the virtual volumes.
